This is a problem I've had since 2008 - Footage taken on my old (horrible) std def, JVC camera.
It came with Cyberlink 9.
My first production came out stretched. Seemed an easy enough problem to cure. But I never could, even though I put in the CPD9 forum this topic:

http://forum.cyberlink.com/forum/posts/list/7813.page

Footage I believe shot in 16:9.
Footage previews perfectly with 16:9 setting.
When produced it comes out stretched, except for when there is a title on screen. It looks like it's DOUBLE widescreen, as if the 16:9 setting has been applied twice somehow.
When I change the aspect to 4:3, I get the conflict message (which ensures me that it was 16:9 in the first place.)
But after production, the footage looks fine, but for bars top and bottom and the picture is still in 16:9 in a 4:3 screen.

Thankfully, I don't have this camera anymore, but was going to try to resolve this problem with this very old footage, and reproduce it so that it is correct. I just can't figure it out, and don't know what to look for.

Am attaching various screenshots and the 16:9 project.

A screenshot of the project when in 16:9, it looks fine.
A screenshot of the project when in 4:3, looks fine but with bars.

The project itself in 16:9

It's so annoying, of all my projects, this is the only one I could never fix. It's 3hrs long in actuality, so a tricky thing to manually fix eachclip! Something must have been wrong with the settings on the camera??? But what can I do to fix this now.
Weird that the preview and the production of 16:9 each look different.

Is the video clip an example of the error? If so, it played perfectly for me. If the original video is 720x480, or the PAL equivalent, it is not actually 16:9, but should produce correctly if you choose the correct profile. What profile are you producing to? __________________________________

Yes Jaime, this clip is an example of the error.
I'm VERY surprised that you say it played ok for you.
On both the preview screen in CL and on Media player, for me, it's first 5 seconds is stretched, the next 15 (where the title starts) is normal, then reverts back to stretched in the next clip of the kids in the hammock. You can only tell by looking at the people, who are stretched horizontally and by the black bars.
what player did you use?

The Custom format I chose thru svrt. It is Mpeg2 720 x 576 25fps 8400k.

What I noticed just now, that is REALLY weird, is that the aspect ratio of the produced clip says 64:27 !!!?
Mathematically, 64:27 is 16:9 x 4:3! What the???
That would make sense to me. Somehow something is stretched,...ie, twice what it should be. So seems the 16:9 original clip, is somehow being stretched again 4:3.

I just don't see how.

Take a look at you profile.ini and see what resolution it says the profile is. I watched the clip in VLC player. I will try it in different players and post some screen shots. __________________________________

What, and where is a profile.ini ??

The original profile of the clip says 16:9
the profile of the produced clip is somehow 64:27 (that's 16:9 x 4:3) resulting in the stretch at times.
weird.

Can you see my screen shots Jaime? The ones that show the stretch? That's what I'm seeing after production, both in preview screen and W media player.

Interjecting here that both shots in the movie look fine. Appears to be 16X9 widescreen standard def which, depending upon player settings, might fill the screen or display with black bars top/bottom. My eyes detect no compression or stretching.

I, too, am not seeing any stretching. I played the clip in VLC, Windows Media Player, Nero Showtime and DivX Player. It played fine in all, although it did play at different resolutions. Media Info says the clip is 720x576. The clips played on my computer at either 720x480 or 848x480. That may give a very slight appearance of stretching, but both are considered 16:9 formats. 720x480 just plays with black bars. Playing the clip on all players I saw no change while playing.

Click on the Windows start button and type profile.ini in the search field and you should find the file. I don't remember the exact path.

Jenny - from your screen shot, I see the extension .MOD. The older JVC camcorders had a proprietary file format that did NOT include the 16:9 flag which most MPEG2 files had. Software companies had to figure a way to recognize and then properly import these files. Granted most software editors do support this format now, but would appear that PD11 is still having an issue. To duplicate your problem, we would need a short .MOD from the camcorder.

That's so weird, when I play it on Media Player, it is OBVIOUSLY stretched, not maybe, or a little bit, but obviously.
I do remember that when I initially made the movies, yes, they're .mod files

, I had to make them on Windows Movie Maker, it was the only player that when produced, it turned out ok.

Now, here's the even weirder thing. When I put these 16:9 clips (they ARE widescreen, definitely), but then use 'set clip attributes' to set the clips 'back' to 4:3, apply to all, then they look fine on cyberlink.

Since the clips are appearing as 64:27 in cyberlink, that's 16:9 x 4:3, I figured if I divided it back again, by 4:3 they'd look normal.
And they do. So I guess I'll do that.

I just can't work out, how you can see it unstretched.!! It's not like it's hard to see. Jenny
